Walk into almost any store this month, and you'll be hit with a wash of pink products -- pink clogs, pink vegetable peelers, pink cleaning products, even pink food -- sold in support of Breast Cancer Awareness Month. Consumers, feeling as if they're participating in the effort to find a cure for the disease, are snapping up pink-tinged everything. And, as a result, nearly all big consumer-products companies are tacking pink ribbons onto their products.

Yet not everything is coming up roses. Some breast-cancer advocates, patients and survivors are questioning whether the pink-ribbon movement has gone too far, with companies seeking higher sales from cause-related packaging without pledging much -- if anything -- in return. It's left up to shoppers to read the labels on pink-packaged products and determine whether their purchase will actually help a breast-cancer charity or foundation, they say."If the label says, 'Money will go to support breast cancer,' well, what does that mean?" says Barbara Brenner, the executive director of advocacy group Breast Cancer Action. "If it says it will support breast cancer awareness without being specific, it's not going anywhere."

Daily Finance surveyed a display of pink-packaged products at a Kmart store and sought to decipher the language on each item. Perhaps the least informative packaging was a pink Swiffer sweeper, made by consumer-products giant Procter & Gamble (PG). The label sports a pink ribbon accompanied by the phrase "early detection saves lives."

So how does purchasing a pink Swiffer help the cause? It's unclear from the label, because it contains no information about how its purchase will help support breast-cancer causes. And, according to a Procter & Gamble spokeswoman, the company will only make a two-cent donation to the National Breast Cancer Foundation if a consumer uses a coupon from Procter & Gamble's brand saver coupon book, which was distributed in newspapers on Sept. 27. Without the coupon, the limited-edition pink packaging on the Swiffer is simply designed to draw awareness to the cause.

The packaging of another product, Herr's Whole Grain Pretzel Ribbons, proclaims that a portion of its sales will be donated to breast cancer awareness and research programs. But there's an asterisk accompanying that statement, which leads to a caveat that Herr's caps its donation at $15,000. A spokeswoman for Herr's didn't immediately return our call seeking a comment.

Capping donations is a particularly prevalent practice among corporations, and it's one that consumers should watch for. According to Samantha King, the author of Pink Ribbons, Inc.: Breast Cancer and the Politics of Philanthropy, "Consumers could be buying a product, and if the maximum has been reached, their product purchase doesn't help."

Part of the confusion about how a pink-ribbon purchase may support the cause can be tied to the fact that no one owns the image or oversees its use, says Brenner of Breast Cancer Action. And because of that, it's difficult to say how much has been raised to help breast-cancer charities, although it's likely in the tens of millions of dollars, King adds.

Of course, some argue that it doesn't matter how the money is raised as long as funds are being donated to help fight the disease. Breast-cancer patient Jeanne Sather, who writes the blog The Assertive Cancer Patient, disagrees.

"Breast cancer is a disease. Not a marketing opportunity," she wrote in an emailed response to Daily Finance's questions. "It also matters that the companies, with a few exceptions, are not donating their own money, they are just passing on their customers' money. Then they are making a profit on top of that --larger than the donation in many if not most cases--and patting themselves on the backs for being good citizens. This is wrong."

Hershey Co. (HSY), for one, says it's both a way to be competitive and support its philanthropic initiatives. The chocolate maker recently began selling a line of Bliss chocolates with pink packaging, which states that the candy maker will donate $300,000 this year in support of the Young Survivors Coalition.

"We see it not only as a competitive business strategy, but one that fits in with our corporate values," says Hershey spokeswoman Jody Cook. "We know the pink ribbon resonates well with our customer, and our main target for the Bliss brand is women and mothers, so it's a perfect fit."

Still, a purchase of Bliss chocolates won't result in a part of the sale going in support of the charity. Cook says Hershey's donation isn't tied to sales of the chocolates, and that the company is clear on its packaging about its donation. Since it's the first year Bliss products have incorporated pink-ribbon branding, the company has yet to determine how the campaign will affect sales of the chocolates, she says.

Yet while pink corporate campaigns have undoubtedly raised millions for breast cancer research and charities, the sheer number of pink-ribboned products makes cancer patients such as Sather feel exploited. Last year, Sather says, she switched grocery stores to Whole Foods (WFMI) simply because it didn't have "lots of pink schlock."

If consumers really want to help fight cancer, they should consider directly giving money to organizations such as Gilda's Club, Team Survivor or Breast Cancer Action, Sather says. Or offer to help a cancer patient personally, such as doing her grocery shopping, she adds.

Despite concerns raised by advocates, it's unclear when the tide of pink-labeled products will slow down. That's because buying pink may just be too simple for many consumers to resist. As Brenner of Breast Cancer Action says, "People have come to believe that if they just do what they're told by corporate America, whether buying a product or doing a walk, they'll solve the breast cancer problem and not have to think about it."
